    "abstract": "We present a simple and practical protocol for the solution of a secure\nmultiparty communication task, the secret sharing, and its experimental\nrealization. In this protocol, a secret message is split among several parties\nin a way that its reconstruction require the collaboration of the participating\nparties. In the proposed scheme the parties solve the problem by a sequential\ncommunication of a single qubit. Moreover we show that our scheme is equivalent\nto the use of a multiparty entangled GHZ state but easier to realize and better\nscalable in practical applications.",
